STRINGSTRING
STRING protein interaction network
Nodes:
Network nodes represent proteins
splice isoforms or post-translational modifications are collapsed, i.e. each node represents all the proteins produced by a single, protein-coding gene locus.
Node Color
colored nodes:
query proteins and first shell of interactors
white nodes:
second shell of interactors
Node Content
empty nodes:
proteins of unknown 3D structure
filled nodes:
a 3D structure is known or predicted
Edges:
Edges represent protein-protein associations
associations are meant to be specific and meaningful, i.e. proteins jointly contribute to a shared function; this does not necessarily mean they are physically binding to each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

nadAQuinolinate synthetase A; Catalyzes the condensation of iminoaspartate with dihydroxyacetone phosphate to form quinolinate. (300 aa)    
Predicted Functional Partners:
nadC
Nicotinate-nucleotide pyrophosphorylase; Involved in the catabolism of quinolinic acid (QA). Belongs to the NadC/ModD family.
 
 
 0.999
nadX
Putative aspartate dehydrogenase; Specifically catalyzes the NAD or NADP-dependent dehydrogenation of L-aspartate to iminoaspartate.
    
 0.938
hypD
Hydrogenase expression/formation protein (maturation factor).
     
 0.793
nadE
NH(3)-dependent NAD(+) synthetase; Catalyzes the ATP-dependent amidation of deamido-NAD to form NAD. Uses ammonia as a nitrogen source.
  
  
 0.626
RCIX762
Putative amidohydrolase.
     
 0.581
nadR
Nicotinamide-nucleotide adenylyltransferase.
     
 0.542
iscS
Class V aminotransferase (NifS-like); Master enzyme that delivers sulfur to a number of partners involved in Fe-S cluster assembly, tRNA modification or cofactor biosynthesis. Catalyzes the removal of elemental sulfur atoms from cysteine to produce alanine. Functions as a sulfur delivery protein for Fe-S cluster synthesis onto IscU, an Fe-S scaffold assembly protein, as well as other S acceptor proteins.
  
  
 0.518
RCIX1570
Class V aminotransferase (NifS-like).
  
  
 0.518
thiL-2
Putative thiamine monophosphate kinase; Catalyzes the ATP-dependent phosphorylation of thiamine- monophosphate (TMP) to form thiamine-pyrophosphate (TPP), the active form of vitamin B1; Belongs to the thiamine-monophosphate kinase family.
     
 0.451
queE
Conserved hypothetical protein; Catalyzes the complex heterocyclic radical-mediated conversion of 6-carboxy-5,6,7,8-tetrahydropterin (CPH4) to 7-carboxy-7- deazaguanine (CDG), a step common to the biosynthetic pathways of all 7-deazapurine-containing compounds.
